Description

Technical Field

[0001] The embodiments of the present application relate to the field of display technology, and in particular, to a display panel and a display device. Background Art

[0002] As electronic display devices are widely used, people have higher requirements for the performance of electronic display devices. Display panels based on technologies such as organic light emitting diodes (OLED) and light emitting diodes (LED) are widely used in various electronic display devices such as mobile phones, televisions, laptops, and desktop computers due to their advantages of high image quality, power saving, and thin body.

[0003] In the process of traditional display panel preparation, the graphicization of luminous pixels is usually achieved through a fine metal mask (FMM). FMM technology is mature and has rich experience in mass production. However, FMM technology also has problems such as limited accuracy, high development cost, and long development cycle. The fine metal mask-free technology eliminates the limitations of traditional OLED processes on display screen size, resolution and other screen performance, and has the advantages of high performance, full-domain size, and agile delivery.

DETAILED DESCRIPTION

[0101] In order to have a clearer understanding of the technical features, purposes and effects of the embodiments of the present application, the specific implementation methods of the embodiments of the present application are now described with reference to the accompanying drawings.

[0102] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0103] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one or more of the parts with the same structure or function are schematically drawn or only one or more of them are marked.

[0104] The present application provides a display panel, referring to Figure 1The display panel includes a substrate 21, a partition structure 22, a plurality of sub-pixels 23, a plurality of inorganic encapsulation parts 31, a plurality of color filter parts 41 and a shading part 42, the partition structure 22 is arranged on one side of the substrate 21, and surrounds and forms a plurality of partition openings; the sub-pixels 23 and the partition openings are arranged correspondingly, and at least part of the sub-pixels 23 are located in the partition openings; the inorganic encapsulation part 31 is arranged on the side of the corresponding sub-pixel 23 away from the substrate 21; the color filter part 41 is superimposed on the side of the corresponding inorganic encapsulation part 31 away from the substrate 21, and the orthographic projection of the partition opening on the substrate 21 is at least partially overlapped with the orthographic projection of the corresponding color filter part 41 on the substrate 21; the shading part 42 is arranged on the side of the partition structure 22 away from the substrate 21, and the orthographic projection of the shading part 42 on the substrate 21 is at least partially overlapped with the orthographic projection of the partition structure 22 on the substrate 21.

[0105] Based on the above technical solution, the present application separates each sub-pixel 23 by a partition structure 22 to prevent the light emission of the sub-pixels 23 from affecting each other. The light shielding portion 42 is arranged on the side of the partition structure 22 away from the substrate 21, and the orthographic projection of the partition opening on the substrate 21 is located within the orthographic projection range of the color filter portion 41 on the substrate 21, so that the light emitting range of the sub-pixel 23 is limited by the light shielding portion 42. Furthermore, the color filter portion 41 is superimposed on the side of the corresponding inorganic encapsulation portion 31 away from the substrate 21, and the orthographic projection of the partition opening on the substrate 21 is located within the orthographic projection range of the color filter portion 41 on the substrate 21, so that the color filter portion 41 can replace the polarizer, thereby improving the light emission efficiency of the sub-pixel 23.

[0106] In one example, the orthographic projection of the partition opening on the substrate 21 is located within the orthographic projection range of the corresponding color filter portion 41 on the substrate 21 .

[0107] Furthermore, the display panel further includes a first inorganic encapsulation layer 32 and a first organic encapsulation layer 33 stacked in sequence in a direction away from the substrate 21, and the first inorganic encapsulation layer 32, the color filter portion 41 and the light shielding portion 42 are all located between the first organic encapsulation layer 33 and the inorganic encapsulation portion 31. In this way, the first inorganic encapsulation layer 32 and the first organic encapsulation layer 33 can protect the first inorganic encapsulation layer 32, the color filter portion 41 and the light shielding portion 42.

[0108] In one example, the first inorganic encapsulation layer 32 is disposed on a side of the inorganic encapsulation portion 31 and the partition structure 22 away from the substrate 21; Figure 1 and Figure 3 One of the color filter portion 41 and the light shielding portion 42 is located on the side of the first inorganic encapsulation layer 32 facing the substrate 21 , and the other is located on the side of the first inorganic encapsulation layer 32 facing away from the substrate 21 .

[0109] Or, in another example, refer to Figure 5 The color filter portion 41 and the light shielding portion 42 are both located on the side of the first inorganic encapsulation layer 32 away from the substrate 21 .

[0110] In one possible implementation, reference Figure 1 , the color filter portion 41 is located in the partition opening, the side of the color filter portion 41 facing away from the substrate 21 is higher than the side of the partition structure 22 facing away from the substrate 21, and the end of the color filter portion 41 is overlapped on the surface of the partition structure 22 facing away from the substrate 21; the first inorganic encapsulation layer 32 and the light shielding portion 42 are sequentially stacked on the side of the color filter portion 41 facing away from the substrate 21 in the direction away from the substrate 21. In this way, by arranging the color filter portion 41 in the partition opening, the distance between the surface of the color filter portion 41 facing away from the substrate 21 and the substrate 21 can be reduced in the thickness direction of the substrate 21, thereby reducing the overall thickness of the display panel. In addition, by arranging the light shielding portion 42 on the side of the first inorganic encapsulation layer 32 facing away from the substrate 21, the adverse effects of the light shielding portion 42 on the inorganic encapsulation portion 31 and the sub-pixel 23 in the manufacturing process can be reduced, and the probability of dark spots appearing on the display panel can be reduced.

[0111] In one example, the material of the light shielding portion 42 includes a black insulating material. For example, the material of the light shielding portion 42 includes a black photoresist material.

[0112] In one example, the light shielding portion 42 is a black matrix.

[0113] In one example, the color filter portion 41 is a color resist. For example, the third filling structure 43 may be formed of a color organic glue.

[0114] The light shielding portion 42 and the color filter portion 41 are used in combination to replace the polarizer and improve the light extraction efficiency of the display panel.

[0115] In one possible embodiment, reference Figure 1 There is a gap between adjacent color filter portions 41, and the first inorganic encapsulation layer 32 contacts the surface of the partition structure 22 on the side away from the substrate 21 at the gap. In this way, the first inorganic encapsulation layer 32 can isolate the adjacent color filter portions 41, and at the same time, the first inorganic encapsulation layer 32 contacts the surface of the partition structure 22 on the side away from the substrate 21, thereby increasing the contact area between the two, improving the bonding ability between the two, and enhancing the encapsulation reliability.

[0116] In an example, the surface of the color filter portion 41 that is away from the substrate 21 is a spherical surface, and the spherical surface is convexly disposed in a direction away from the substrate.

[0117] In one example, the surface of the light shielding portion 42 facing away from the substrate 21 is a plane.

[0118] In one example, the orthographic projection of the light shielding portion 42 on the substrate 21 is located within the orthographic projection range of the partition structure 22 on the substrate 21 , or overlaps with the orthographic projection of the partition structure 22 on the substrate 21 .

[0119] In one possible embodiment, reference Figure 2 The display panel further includes a retaining wall 51, the display panel includes a display area A0 and a non-display area A1, the display panel includes a retaining wall 51 and a stopper 52 located in the non-display area A1, the retaining wall 51 is arranged on one side of the substrate 21, the first inorganic encapsulation layer 32 is continuously distributed in the display area and the non-display area, and the first organic encapsulation layer 33 is located on the side of the retaining wall 51 facing the display area. In this way, when the first organic encapsulation layer 33 is manufactured, the retaining wall 51 can be used to prevent the overflow of the first organic encapsulation layer 33, so that the first organic encapsulation layer 33 can cover the light shielding part 42, the color filter part 41 and the first inorganic encapsulation layer 32 in the display area.

[0120] In one example, reference Figure 2 The stopper 52 and the first inorganic encapsulation layer 32 are sequentially stacked on the side of the retaining wall 51 away from the substrate 21 in a direction away from the substrate 21, and the material of the stopper 52 is the same as that of the color filter 41. In this way, the stopper 52 can increase the height of the retaining wall 51, thereby effectively preventing the overflow of the first organic encapsulation layer 33. In the process of manufacturing the display panel, the stopper 52 and the color filter 41 can be obtained through the same process.

[0121] Optionally, there are two retaining walls 51 , which are spaced apart from each other in a direction from the display area to the non-display area, and there are two stoppers 52 , which are respectively overlapped on the two retaining walls 51 .

[0122] In another possible implementation, refer to Figure 3, the display panel also includes a second organic layer 34, which is located on the side of the first inorganic encapsulation layer 32 facing the substrate 21; the shading portion 42 is stacked on the surface of the partition structure 22 on the side away from the substrate 21, and the second organic layer 34 covers the shading portion 42 and the inorganic encapsulation portion 31; the color filter portion 41 is stacked on the surface of the first inorganic encapsulation layer 32 on the side away from the substrate 21. In this way, by stacking the shading portion 42 on the surface of the partition structure 22 on the side away from the substrate 21, the sub-pixel 23 can have a larger light output angle. By stacking the color filter portion 41 on the surface of the first inorganic encapsulation layer 32 on the side away from the substrate 21, the adverse effects of the color filter portion 41 on the inorganic encapsulation portion 31 and the sub-pixel 23 in the manufacturing process can be reduced, and the probability of dark spots appearing on the display panel can be reduced. In addition, the partition opening is filled by the second organic layer 34, that is, the film layer is flattened to avoid the poor flatness of the first organic encapsulation layer 33 in the encapsulation film layer, which affects the encapsulation reliability. For example, when the display panel is applied to a folding display panel or a flexible display panel, since the partition structure 22 is made of metal material and the morphology of the partition structure 22 is irregular, there is a stress concentration area, so the packaging film layer may be damaged when it is bent or curved, thereby affecting the packaging reliability; and the present application fills the partition opening with a second organic layer 34. While ensuring the flatness of the film layer, the organic layer will release the stress in the stress area, and at the same time cooperate with the first inorganic packaging layer 32 to improve the packaging reliability.

[0123] In an example, the surface of the color filter portion 41 that is away from the substrate 21 is a spherical surface, and the spherical surface is convexly disposed in a direction away from the substrate.

[0124] In one example, the surface of the light shielding portion 42 facing away from the substrate 21 is a plane.

[0125] In one example, the orthographic projection of the light shielding portion 42 on the substrate 21 is located within the orthographic projection range of the partition structure 22 on the substrate 21 , or overlaps with the orthographic projection of the partition structure 22 on the substrate 21 .

[0126] In one example, the material of the second organic layer 34 includes transparent photoresist.

[0127] In one possible embodiment, reference Figure 4The display panel further includes a retaining wall 51, the display panel includes a display area A0 and a non-display area A1, the display panel includes a retaining wall 51 and a stopper 52 located in the non-display area, the retaining wall 51 is arranged on the side of the substrate 21 facing the sub-pixel 23, the first inorganic encapsulation layer 32 is continuously distributed in the display area and the non-display area, and the first organic encapsulation layer 33 is located on the side of the retaining wall 51 facing the display area. When manufacturing the first organic encapsulation layer 33, the retaining wall 51 can be used to prevent the overflow of the first organic encapsulation layer 33, so that the first organic encapsulation layer 33 can cover the light shielding part 42, the color filter part 41 and the first inorganic encapsulation layer 32 in the display area.

[0128] In one example, reference Figure 4 The stopper 52 and the first inorganic encapsulation layer 32 are sequentially stacked on the side of the retaining wall 51 away from the substrate 21 in a direction away from the substrate 21, and the material of the stopper 52 is the same as that of the light shielding portion 42. In this way, the stopper 52 can increase the height of the retaining wall 51, so as to effectively prevent the overflow of the first organic encapsulation layer 33. In the process of manufacturing the display panel, the stopper 52 and the light shielding portion 42 can be obtained through the same process.

[0129] In another possible implementation, refer to Figure 5 , the display panel also includes a second organic layer 34, which is located on the side of the first inorganic encapsulation layer 32 facing the substrate 21, and the light shielding portion 42 and the color filter portion 41 are both arranged on the surface of the first inorganic encapsulation layer 32 on the side away from the substrate 21; along the extension direction of the substrate 21, the light shielding portion 42 and the color filter portion 41 are alternately distributed, and the two ends of the color filter portion 41 overlap the light shielding portion 42. In this way, by stacking the color filter portion 41 and the light shielding portion 42 on the surface of the first inorganic encapsulation layer 32 on the side away from the substrate 21, the adverse effects on the inorganic encapsulation portion 31 and the sub-pixel 23 during the manufacturing process of the color filter portion 41 and the manufacturing process of the light shielding portion 42 can be reduced, and the probability of dark spots appearing on the display panel can be reduced. At the same time, the second organic layer 34 and the light shielding portion 42 are separated by the first inorganic encapsulation layer 32, which can avoid the risk of the second organic layer 34 and the light shielding portion 42 being mutually dissolved.

[0130] In one example, the orthographic projection of the light shielding portion 42 on the substrate 21 is located within the orthographic projection range of the partition structure 22 on the substrate 21 , or overlaps with the orthographic projection of the partition structure 22 on the substrate 21 .

[0132] In one example, the color filter portion 41 is a color resist. For example, the third filling structure 43 may be formed of a color organic glue.

[0133] The light shielding portion 42 and the color filter portion 41 are used in combination to replace the polarizer and improve the light extraction efficiency of the display panel.

[0134] In one example, the material of the second organic layer 34 includes transparent photoresist.

[0135] In one example, the surface of the color filter portion 41 facing away from the substrate 21 is a spherical surface, and the spherical surface is convexly arranged in a direction away from the substrate. By making the surface of the first inorganic encapsulation layer 32 facing away from the substrate 21 a plane, the morphology of the color filter portion 41 can be improved, which is conducive to the color filter portion 41 having a spherical surface.

[0136] Optionally, the surface of the light shielding portion 42 facing away from the substrate 21 is a plane.

[0137] In one possible embodiment, reference Figure 6 The display panel further includes a retaining wall 51, the display panel includes a display area A0 and a non-display area A1, the display panel includes a retaining wall 51 and a stopper 52 located in the non-display area, the retaining wall 51 is arranged on the side of the substrate 21 facing the sub-pixel 23, the first inorganic encapsulation layer 32 is continuously distributed in the display area and the non-display area, and the first organic encapsulation layer 33 is located on the side of the retaining wall 51 facing the display area. The stopper 52 and the first inorganic encapsulation layer 32 are sequentially stacked on the side of the retaining wall 51 away from the substrate 21 in the direction toward the substrate 21. In this way, when the first organic encapsulation layer 33 is manufactured, the retaining wall 51 can be used to prevent the overflow of the first organic encapsulation layer 33, so that the first organic encapsulation layer 33 can cover the light shielding part 42, the color filter part 41 and the first inorganic encapsulation layer 32 in the display area. The stopper 52 can increase the height of the retaining wall 51, so as to effectively prevent the overflow of the first organic encapsulation layer 33.

[0138] Optionally, the material of the stopper 52 is the same as that of the second organic layer 34. In the process of manufacturing the display panel, the stopper 52 and the second organic layer 34 can be obtained through the same process.

[0140] In one possible implementation, reference Figure 2 The display panel further includes a second inorganic encapsulation layer 35, which is stacked on the side of the first organic encapsulation layer 33 away from the substrate 21. In this way, by providing the second inorganic encapsulation layer 35, the first organic encapsulation layer 33 can be protected.

[0141] Optionally, the orthographic projection of the first organic encapsulation layer 33 on the substrate 21 is located within the orthographic projection range of the second inorganic encapsulation layer 35 on the substrate 21 .

[0142] Optionally, the orthographic projection of the first inorganic encapsulation layer 32 on the substrate 21 is located within the orthographic projection range of the second inorganic encapsulation layer 35 on the substrate 21 .

[0143] In one possible implementation, reference Figure 1 , the plurality of sub-pixels 23 include a first sub-pixel 23, a second sub-pixel 23 and a third sub-pixel 23, the partition opening includes a first partition opening, a second partition opening and a third partition opening, the first sub-pixel 23 is arranged corresponding to the first partition opening, the second sub-pixel 23 is arranged corresponding to the second partition opening, and the third sub-pixel 23 is arranged corresponding to the third partition opening; the first sub-pixel 23 and the second sub-pixel 23 have different luminous colors, the first sub-pixel 23 and the third sub-pixel 23 have different luminous colors, and the second sub-pixel 23 and the third sub-pixel 23 have different luminous colors.

[0144] The color of light that can be transmitted by the color filter 41 is the same as the color of the light emitted by the corresponding sub-pixel 23. In this way, the color filter 41 can accurately select a small range of light waves to be transmitted, and reflect other undesirable light waves, so that the human eye can receive saturated light of a certain color, achieving the effect of replacing a polarizer and avoiding glare or color deviation.

[0145] In one possible implementation, reference Figure 1 The display panel further includes a pixel defining layer 24, which is disposed between the substrate 21 and the partition structure 22. The pixel defining layer 24 includes a plurality of pixel openings, the pixel openings correspond to the partition openings, and the orthographic projection of the pixel openings on the substrate 21 is located within the orthographic projection range of the partition openings on the substrate 21; some sub-pixels 23 are disposed in the pixel openings; wherein the sub-pixels 23 include a first electrode 231, a light emitting structure 232, and a second electrode 233 sequentially stacked in a direction away from the substrate 21, the first electrode 231 is disposed between the substrate 21 and the pixel defining layer 24, at least a portion of the first electrode 231 is exposed in the pixel opening, and the light emitting structure 232 is stacked on the surface of the first electrode 231 exposed in the pixel opening. In this way, the partition structure 22 can separate adjacent sub-pixels 23 to prevent adjacent sub-pixels 23 from interfering with each other. Under the conductive action of the first electrode 231 and the second electrode 233, the light emitting structure 232 can emit light, and the light emitting range of the light emitting structure 232 is the range defined by the partition opening.

[0146] Optionally, the second electrode 233 is electrically connected to the partition structure 22 . In this way, the second electrodes 233 can be electrically connected to each other through the partition structure 22 , which is conducive to achieving uniform conductivity of the second electrodes 233 .

For example, the second electrode 233 and the second structure layer 2202 are in conductive contact to achieve electrical connection. In this way, the first structure layer 2201 can extend out of the side wall of the second structure layer 2202 to form an eaves-like structure. Then, when the second electrode 233 is evaporated, the second electrode 233 will not be continuous near the eaves-like structure, but will be discontinuous. In this way, the partition structure 22 can reliably separate adjacent second electrodes 233.

[0148] In one example, the partition structure 22 further includes a third structure layer 2203, which is disposed between the second structure layer 2202 and the pixel defining layer 24, and the orthographic projections of the third structure layer 2203 and the second structure layer 2202 on the substrate 21 are both located within the orthographic projection range of the first structure layer 2201 on the substrate 21, and the orthographic projection of the second structure layer 2202 on the substrate 21 is located within the orthographic projection range of the first structure layer 2201 on the substrate 21. In this way, the first structure layer 2201 not only extends out of the side wall of the second structure layer 2202, but also extends out of the side wall of the third structure layer 2203, so that the second electrode 233 can be reliably made discontinuous near the eaves-shaped structure.

[0149] For example, the material of the first structure layer 2201 includes titanium or molybdenum, the material of the second structure layer 2202 includes aluminum or copper or silver, and the material of the third structure layer 2203 includes titanium or molybdenum.

[0150] In one possible embodiment, reference Figure 1 The display panel further includes a driving circuit layer 25, which is disposed between the pixel defining layer 24 and the substrate 21. The first electrode 231 is located on the side of the driving circuit layer 25 away from the substrate 21, and the first electrode 231 is electrically connected to the driving circuit in the driving circuit layer 25. In this way, the light emission of the sub-pixel 23 can be controlled by the electrical connection between the driving circuit and the first electrode 231.

[0151] Specifically, the driving circuit layer 25 may include an insulating material layer and a driving conductive structure arranged in the insulating material layer. A via is arranged on the insulating material layer, and the first electrode 231 is connected to the driving conductive structure through the via, thereby realizing electrical connection between the first electrode 231 and the driving circuit layer 25.

[0152] The display panel may further include a driving chip, which is disposed in the frame area, and the driving circuit layer 25 is electrically connected to the driving chip. In this way, the driving circuit layer 25 can play a conductive role between the driving chip and the sub-pixels.

[0153] This application also provides another display panel, referring to Figure 1 , Figure 3 and Figure 5 The display panel includes a substrate 21, a partition structure 22, a plurality of sub-pixels 23, a plurality of inorganic encapsulation parts 31, a plurality of color filter parts 41, a light shielding part 42, and a first inorganic encapsulation layer 32 and a first organic encapsulation layer 33 stacked in sequence in a direction away from the substrate 21, the partition structure 22 is arranged on one side of the substrate 21, and surrounds and forms a plurality of partition openings; the sub-pixels 23 and the partition openings are arranged correspondingly, and at least part of the sub-pixels 23 are located in the partition openings; the inorganic encapsulation part 31 is arranged on the side of the corresponding sub-pixel 23 away from the substrate 21; the color filter part 41 is arranged on the side of the corresponding inorganic encapsulation part 31 away from the substrate 21; the light shielding part 42 is stacked on the side of the corresponding partition structure 22 away from the substrate 21, and the orthographic projection of the light shielding part 42 on the substrate 21 and the orthographic projection of the partition structure 22 on the substrate 21 at least partially overlap;

[0154] Among them, the color filter portion 41 and the shading portion 42 are both located on the side of the first inorganic encapsulation layer 32 away from the substrate 21, or, one of the color filter portion 41 and the shading portion 42 is located on the side of the first inorganic encapsulation layer 32 facing the substrate 21, and the other is located between the first inorganic encapsulation layer 32 and the first organic encapsulation layer 33.

[0155] Based on the above technical solution, the present application separates each sub-pixel 23 by a partition structure 22 to prevent the light emission of the sub-pixels 23 from responding to each other. The shading portion 42 is arranged on the side of the partition structure 22 away from the substrate 21, and the orthographic projection of the partition opening on the substrate 21 is located within the orthographic projection range of the color filter portion 41 on the substrate 21, so that the light emitting range of the sub-pixel 23 is limited by the shading portion 42. Further, the color filter portion 41 is superimposed on the side of the corresponding inorganic encapsulation portion 31 away from the substrate 21, and the orthographic projection of the partition opening on the substrate 21 is located within the orthographic projection range of the color filter portion 41 on the substrate 21, so that the color filter portion 41 can replace the polarizer, thereby improving the light emission efficiency of the sub-pixel 23. In addition, the first inorganic encapsulation layer 32 and the first organic encapsulation layer 33 can protect the first inorganic encapsulation layer 32, the color filter portion 41 and the shading portion 42.

In this way, by arranging the color filter portion 41 in the partition opening, the distance between the surface of the color filter portion 41 facing away from the substrate 21 and the substrate 21 can be reduced in the thickness direction of the substrate 21, thereby reducing the overall thickness of the display panel. In addition, by arranging the light shielding portion 42 on the side of the first inorganic encapsulation layer 32 facing away from the substrate 21, the adverse effects of the light shielding portion 42 on the inorganic encapsulation portion 31 and the sub-pixel 23 in the manufacturing process can be reduced, and the probability of dark spots appearing on the display panel can be reduced.

[0160] The light shielding portion 42 and the color filter portion 41 are used in combination to replace the polarizer and improve the light extraction efficiency of the display panel.

[0161] In one example, there is a gap between adjacent color filter portions 41, and the first inorganic encapsulation layer 32 contacts the surface of the partition structure 22 facing away from the substrate 21 at the gap. In this way, the first inorganic encapsulation layer 32 can isolate adjacent color filter portions 41 to enhance encapsulation reliability.

[0162] In another possible implementation, refer to Figure 3 , the display panel also includes a second organic layer 34, which is located on the side of the first inorganic encapsulation layer 32 facing the substrate 21; the light shielding portion 42 is stacked on the surface of the partition structure 22 on the side away from the substrate 21, and the second organic layer 34 covers the light shielding portion 42 and the inorganic encapsulation portion 31; the color filter portion 41 is stacked on the surface of the first inorganic encapsulation layer 32 on the side away from the substrate 21. In this way, by stacking the light shielding portion 42 on the surface of the partition structure 22 on the side away from the substrate 21, the sub-pixel 23 can have a larger light output angle. By stacking the color filter portion 41 on the surface of the first inorganic encapsulation layer 32 on the side away from the substrate 21, the adverse effects of the color filter portion 41 on the inorganic encapsulation portion 31 and the sub-pixel 23 in the manufacturing process can be reduced, and the probability of dark spots appearing on the display panel can be reduced.

[0163] Alternatively, refer to Figure 5 , the second organic layer 34 is located on the side of the first inorganic encapsulation layer 32 facing the substrate 21, and the light shielding portion 42 and the color filter portion 41 are both arranged on the surface of the first inorganic encapsulation layer 32 on the side away from the substrate 21; along the extension direction of the substrate 21, the light shielding portion 42 and the color filter portion 41 are alternately distributed, and the two ends of the color filter portion 41 overlap the light shielding portion 42. In this way, by stacking the color filter portion 41 and the light shielding portion 42 on the surface of the first inorganic encapsulation layer 32 on the side away from the substrate 21, the adverse effects on the inorganic encapsulation portion 31 and the sub-pixel 23 during the manufacturing process of the color filter portion 41 and the manufacturing process of the light shielding portion 42 can be reduced, and the probability of dark spots appearing on the display panel can be reduced. At the same time, by using the first inorganic encapsulation layer 32 to separate the second organic layer 34 and the light shielding portion 42, the risk of the second organic layer 34 and the light shielding portion 42 being mutually dissolved can be avoided.

At the same time, by using the first inorganic encapsulation layer 32 to separate the second organic layer 34 and the light shielding 42, the risk of the second organic layer 34 and the light shielding 42 being mutually dissolved can be avoided.

[0188] The light shielding portion 42 can be obtained by first coating to form a black photoresist layer, and then exposing and developing the black photoresist layer. The color filter portion 41 can be obtained by first coating to form a color organic glue layer, and then exposing and developing the color organic glue layer.

[0189] The second organic layer 34 can be obtained by coating a transparent photoresist material layer. The display panel includes a display area A0 and a non-display area A1, and the display panel may include a retaining wall 51 located in the non-display area. In the process of coating the transparent photoresist material layer to obtain the second organic layer 34, a transparent photoresist material layer is also coated on the retaining wall 51. Then, the transparent photoresist material layer in the display area and the transparent photoresist material layer on the retaining wall 51 can be retained by exposure and development, thereby obtaining the second organic layer 34 and the stopper 52 stacked on the retaining wall 51, and the stopper 52 and the second organic layer 34 are made of the same material, as shown in FIG. Figure 6 .
